   Dark-committed. Kinetic Syne display type, layered depth (the brand is
   literally called parallax), native scroll-driven animation, cross-document
   view transitions, oklch wide-gamut brand color. Zero frameworks, zero
   build step. Motion is progressive enhancement: reduced-motion and older
   engines get the final, fully readable state.
